Merge tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrlgrafted

Pull pin control updates from Linus Walleij:
 "Core changes:

   - Use the non-blocking mux_state_try_select() in the generic MUX pin
     control back-end

   - Free pin maps on pinctrl_generic_to_map() failure in the core
     helpers

  New hardware pin control:

   - Qualcomm Maili TLMM SoC, PMG1110 PMIC, and Eliza LPASS LPI TLMM SoC
     (this is for the low power audio, LPASS = Low Power Audio SubSystem
     portions)

   - Upboard support on top of the Intel pin controller

   - Apple T6030 and T6031 support (just compatible strings)

   - Samsung Exynos 8855 SoC

   - Mediatek MT6858 SoC

   - Rockchip RK3308B and RV1106 SoCs

   - Airoha EN7523 and AN7563 SoCs

  Improvements:

   - Qualcomm TLMM GPIOs are unconditionally marked as wakeup capable

   - Qualcomm improvements on top of the Qualcomm PDC (power domain
     controller) irqchip improvements from tglx:s tree

   - Qualcomm IPQ806x and IPQ9650 non-urgent pin grop fixups

   - The NPCM8xx driver has been put into shape fixing many pin and
     group definitions

   - Some non-urgent Tegra 264 pin assignments are fixed up

   - Some non-urgent fixups to Airoha AN7581 and AN7583 registers and
     pin assignments, missing features etc"

+ * Prolific PL-2301/PL-2302 driver ... http://www.prolific.com.tw/
+ *
+ * The protocol and handshaking used here should be bug-compatible
+ * with the Linux 2.2 "plusb" driver, by Deti Fliegl.
+ *
+ * HEADS UP:  this handshaking isn't all that robust.  This driver
+ * gets confused easily if you unplug one end of the cable then
+ * try to connect it again; you'll need to restart both ends. The
+ * "naplink" software (used by some PlayStation/2 developers) does
+ * the handshaking much better!   Also, sometimes this hardware
+ * seems to get wedged under load.  Prolific docs are weak, and
+ * don't identify differences between PL2301 and PL2302, much less
+ * anything to explain the different PL2302 versions observed.
+ *
+ * NOTE:  pl2501 has several modes, including pl2301 and pl2302
+ * compatibility.   Some docs suggest the difference between 2301
+ * and 2302 is only to make MS-Windows use a different driver...
+ *
+ * pl25a1 glue based on patch from Tony Gibbs.  Prolific "docs" on
+ * this chip are as usual incomplete about what control messages
+ * are supported.
